Adp can convert to atp during .
a)oxidation
b)phosphorylation
c)dephosphorylation

Option B,

Explanation:

ADP consists of two phosphate group and ATP consists of three phosphate group. Thus ADP can be converted to ATP if one phosphate group is added to it.

In the process of phosphorylation, a phosphate group is added  to Adenosine di phosphate (ADP) to make Adenosine tri phosphate (ATP). This process takes place inside the mitochondrial matrix during the kerb cycle process

Hence, option B is correct

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products
